between appropriability mechanisms, innovation and firm-level productivity. We enrich this model in several ways. First, we … consider different types of innovation spending and study the differences in estimates when innovation spending (rather than R …&D spending) is used to predict innovation in the CDM model. Second, we assume that a firm simultaneously innovates and chooses …

This paper focuses on developing and adapting statistical models of counts (non-negative integers) in the context of panel data and using them to analyze the relationship between patents and R&D expenditures. The model used is an application and generalization of the Poisson distribution to...

We develop a forward‐looking profit model to estimate the depreciation rates of business R&D capital. By using data from BEA and NSF between 1987 and 2007, and the newly developed model, we estimate both constant and time‐varying industry‐specific R&D depreciation rates. The results...

This paper investigates the dynamics of firm growth in the U. S.manufacturing sector in the recent past. I use panel data on thepublicly traded firms in the U. S. manufacturing sector: from auniverse of approximately 1800 firms in 1976, I am able to follow mostof them for at least three years,...
